In 2008 the RIVM actualised the 'framework of reference' for ambulance care. This framework is used to calculate the geographical distribution and the capacity of ambulance care required in each region of the Netherlands. It is based on a set of national uniform preconditions and the actual need for ambulance care and incorporates the most recent data. This report describes the two models that are used in the framework: the driving-time model and the capacity model.<br>The driving-time model is an instrument to determine the geographical coverage. This model estimates the time needed for an ambulance to drive from one arbitrary point to another in response to an emergency call. The capacity model calculates the number of ambulances required to adequately meet the demand for ambulance care. It also provides a safeguard for the regional preparedness of ambulance care.<br>The models are both appropriate and suitable for use in the 'framework of reference'. The pre-determined limiting conditions and starting points appear to fit into the respective models. The report also suggests a number of recommendations to improve the model for future applications. The driving-time model should be updated regularly. Additionally, capacity models used in countries other than the Netherlands should be studied with the aim of further improving the appropriateness of the Dutch models. Among other options, thought should also be given to incorporating efficiency incentives into the models.<br>
